LG Washer Door Gasket Replacement for Mold and Odor in Lakewood, CO
A homeowner in Lakewood contacted Denver Rapid Appliance Repair after noticing a persistent, unpleasant odor coming from their LG front-load washer. When our technician arrived and opened the door, the source was immediately clear: the rubber door gasket had accumulated extensive mold and residue throughout its folds. Because the contamination was too deep to clean effectively, we recommended replacing the gasket entirely — and completed the repair the same visit.

Why Front-Load Washer Gaskets Develop Mold
Front-load washers are highly efficient, but the horizontal drum design means the door gasket sits at the bottom of the door opening where water, detergent residue, and lint can collect after every cycle. The deep folds of the rubber bellow create pockets that stay damp long after the wash is done — an ideal environment for mold and mildew to take hold.
Over time, that mold works its way deeper into the rubber and can transfer odors to laundry even when the washer appears clean on the surface. In this case, the buildup had progressed to the point where cleaning was no longer a practical solution — the gasket needed to come out.
Our Repair Process
After confirming the diagnosis, Cody removed the mold-contaminated door gasket and prepared the drum opening for the new bellow. Installing a front-load washer door gasket correctly requires proper tooling — the inner retaining spring must be expanded and seated evenly before the outer spring is secured, or the gasket can shift and leak.
- Removed the old mold-contaminated door boot gasket.
- Cleaned the drum lip and door frame before installing the new gasket.
- Used LG spring-expansion pliers to properly seat the inner retaining spring.
- Secured the outer door-gasket spring around the full perimeter.
- Ran the washer through LG diagnostic testing to verify proper operation.
- Performed a leak test around the newly installed gasket — no leaks found.
How to Slow Mold Buildup on a Front-Load Washer Gasket
No gasket lasts forever, but a few habits can significantly extend its life and keep odors from developing:
- Leave the washer door slightly ajar after every load to allow the drum and gasket to dry.
- Wipe the gasket folds dry with a towel after each use, especially the bottom pocket.
- Use only HE (high-efficiency) detergent and avoid overpouring — excess suds leave residue.
- Run a monthly tub-clean cycle with a washer cleaner tablet.
- Inspect the gasket periodically for early signs of mold so it can be addressed before it spreads.
Signs Your LG Washer Gasket May Need Replacement
- Persistent musty or sour odor even after running a clean cycle.
- Visible black or dark mold embedded in the rubber folds.
- Laundry coming out smelling worse than it went in.
- Tears, cracks, or stiffness in the rubber bellow.
- Water leaking from the front of the machine during a cycle.
If cleaning no longer eliminates the odor, replacement is usually the most effective long-term solution.
